Xianrui Dong discovered that libheif had an out-of-bounds read in its HEIF sequence track parser. An attacker could possibly use this issue to cause a denial of service or obtain sensitive information. This issue only affected Ubuntu 26.04 LTS. (CVE-2026-47254) Junyi Liu discover…
Harry Sintonen discovered that curl incorrectly handled credentials when following HTTP redirects in conjunction with .netrc files. An attacker could possibly use this issue to obtain sensitive information. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, and Ubuntu 1…
It was discovered that Python did not use sufficient entropy for Expat hash-flooding protection in the xml.parsers.expat and xml.etree.ElementTree modules. An attacker could use this to cause a denial of service via a crafted XML document.
Eric Su and Samuel Dainard discovered that libsoup incorrectly handled content with zero-length resources. An attacker could possibly use this issue to trigger a buffer over-read, resulting in information disclosure or a denial of service. This issue only affected Ubuntu 18.04 LT…
It was discovered that LibRaw incorrectly handled certain Nikon RAW image files. An attacker could possibly use this issue to cause LibRaw to crash, resulting in a denial of service. (CVE-2026-5342) It was discovered that LibRaw had an integer overflow in its DNG image loader. An…
It was discovered that Libidn incorrectly handled certain internationalized domain name strings. An attacker could possibly use this issue to obtain sensitive information or cause a denial of service.
It was discovered that Expat used insufficient entropy when generating hash salt values for its internal hash table. An attacker could use this to craft an XML document that triggers hash flooding, leading to a denial of service.
Jakub Ciolek and Nicola Murino discovered that Go Cryptography incorrectly handled SSH agent responses. An attacker could use this to cause a denial of service. (CVE-2025-47913) Yuichi Watanabe discovered that Go Cryptography incorrectly handled SSH key exchanges. An attacker cou…
Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - ARM64 architecture; - MIPS architecture; - PowerPC architecture; - x86 architecture; - Block layer…
Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - ARM64 architecture; - Block layer subsystem; - Cryptographic API; - DMA engine subsystem; - Infini…
Aaron Rainbolt discovered that the cautious-launcher utility in the mailcap package did not properly restrict the execution of certain file types. An attacker could use this issue to escape a sandboxed application and execute arbitrary code on the host operating system.
It was discovered that ClamAV incorrectly handled certain PE files. A remote attacker could possibly use this issue to cause ClamAV to crash, resulting in a denial of service. (CVE-2026-20213, CVE-2026-20214, CVE-2026-20217) It was discovered that ClamAV incorrectly handled certa…
It was discovered that Apache HTTP Server's mod_ldap module incorrectly handled memory when processing per-directory configurations. An attacker could use this issue to cause the server to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2026-2916…
It was discovered that Addressable incorrectly handled certain URI templates, generating regular expressions vulnerable to catastrophic backtracking. An attacker could use this issue to craft a URI that, when matched against a vulnerable template, causes excessive resource consum…
It was discovered that OpenSSH incorrectly handled file permissions when downloading files as root using the legacy scp protocol without the preserve-mode option. An attacker could use this to install setuid or setgid files on a system, possibly leading to privilege escalation.
It was discovered that GnuTLS had a timing side-channel when processing malformed ciphertexts in RSA-PSK ClientKeyExchange. A remote attacker could possibly use this issue to recover sensitive information. This issue only affected Ubuntu 18.04 LTS. (CVE-2024-0553) Bing Shi discov…
It was discovered that PHP incorrectly handled SOAP object deduplication when processing apache:Map nodes with duplicate keys. An attacker could possibly use this to cause a use-after-free, resulting in remote code execution. (CVE-2026-6722) It was discovered that PHP incorrectly…
It was discovered that Gzip's gzexe utility handled temporary files in an insecure manner. When the mktemp utility was not available, gzexe constructed a temporary file path based on the process ID, which could be predicted. A local attacker could possibly use this issue to overw…
